Monolithic Power Systems MP4026

Description

The MP4026 is a primary-side-control, offline LED controller that achieves high-power factorand accurate LED current for isolated, singlepower-stage lighting applications in an FCTSOT package. It is the next generation of the successful MP4021A. The proprietary realcurrent-control method accurately controls LED current from primary-side information with goodline and load regulation. The primary-side-control eliminates the secondary-side feedback components and the opto-coupler to significantlysimplify LED-lighting-system design.The MP4026 integrates power-factor correction and works in boundary-conduction mode to reduce MOSFET switching losses.The MP4026’s multiple protection features greatly enhance system reliability and safety. These features include over-voltage protection,short-circuit protection, primary-side over-current protection, brown out protection, cycle-by-cycle current limiting, VCC under-voltage lockout, and auto-restart over-temperature protection.
